Offshore engineering involves uncertainty. We bring clarity to muddy waters.
Offshore engineering can involve lots of risk and uncertainty. But confident business decisions come from knowing exactly where you stand. Let us help.
Get the opinion of an offshore expert. Plot your path forward.
Offshore engineering involves big decisions – the commercial ramifications of which can be huge. When you are facing uncertainty, it can be beneficial to get a second opinion. Especially when that opinion is provided by an independent, experienced ocean engineering expert.
With an in-house team of geotechnical and geophysical experts – not to mention a decade’s worth of input on successful offshore developments across the globe – we are well positioned to provide you with clear, professional insight.
Perhaps a certain aspect of a project hasn’t gone as smoothly as you hoped. That’s common in a technically demanding sector like offshore engineering. We can provide a clear opinion about where you stand and help you plan what to do next. We’ve even been called as an expert witness during legal proceedings.
Whatever type of insight you need, our experts are on hand to give you clarity.
We can provide support with:
- Site viability and bidding strategy
- Technical due diligence
- Dispute resolution
- Provision of an expert witness

FAQs
Is it cost effective to work with an expert?
Offshore development requires significant capital investment. Commercial sensitivity is crucial to make sure your project recoups the investment and operates profitably. That’s precisely why you should work with an expert who has the comprehensive engineering expertise and project experience to maintain commercial focus. The more you involve us in your project, the more we can derisk it and prevent costly mistakes.
What do you mean by commercially aware?
Engineering errors cost money. Much of what we do is concerned with risk reduction. Because we understand that you have certain commercial ambitions for your development.
